Contestia and RTTYMCreator : Nick Fedoseev (UT2UZ) in 2005Description : The Contestia and RTTYM modes are directly derived from the Olivia mode (Pawel Jalocha SP9VRC) but with a different compromise between speed and robustness

Block size (symbols) Contestia:32 RTTYM :16

Characters set : Contestia : bitschar -> decimal code

0 (idling) -> 0

Space -> 59

<CR> -> 60

CHR(33) à CHR(90) ->1 à 58

Multipsk specificity:<BS> (key<---) -> 61

Small letters are transformed in capital letters

RTTYM: Same set of characters as for standard RTTY,except that the "letters" character is the CHR(0) instead the CHR(31) one

The idling character is the CHR(31) character.

Multipsk specificity:

<Bell> is coded as @ (second ' in Mixw)

For Contestia (terms "Slow"...qualify the sub-mode speed by comparison with the mean speed in Contestia):

* CONTESTIA is a bit less sensitive than Olivia (+1.5 dB on minimum S/N). It is a also a bit less robust (due to a smaller block size) but it is twice more rapid (with a reduce set of characters). This mode is an excellent chat mode (because sensitive and rapid).

* RTTYM is a less sensitive than Olivia (+ 3 dB on minimum S/N). It is also less robust (due to a small block size and due to the RTTY problem of random shift from letters to figures or reversely, on an error) but it is almost four times more rapid (with the RTTY set of characters). This mode is interesting for very quick QSO.

eQSL checkt to see if you have any eQSL cards!
